I am making a project in react native and I have installed all the dependencies for it but when I run the code it shows

TypeError: undefined is not an object (evaluating '_reactNative.Stylesheet.create')

at first it said something about one of the functions which I fixed but I don't understand where it is referencing the undefined object, if anyone can find what file or function it is talking about, that would be great.

Please try something like this

const styles = StyleSheet.create({ 
  _container: { 
    flex: 1, 
    backgroundColor: 'blue', 
    alignItems: 'center', 
    justifyContent: 'center' 
  }, 
  get container() { 
    return this._container; 
  }, 
  set container(value) { 
    this._container = value; 
  }, 
});
